You would perhaps not say, but there is still a forest of memory cards of different types. In consumer devices, we have sd and the smaller micro sd variant. Sony’s MemoryStick Duo, which today is part of Sony products in the same SD slot, still exists. In the professional segment, with larger devices, we CompactFlash, CFast and XQD. The battle is the standard for some time behind us. This was won by the compact SD card, which is used in a variety of devices and is supported by virtually every laptop. Also, almost all cameras support SD cards.

Floppy and SD cards

Fifteen 64GB SD cards have as much capacity as 2.67 million floppy disks

Nevertheless, the SD card is no longer the most popular format. That role has been taken over by the micro-SD card, a much smaller one in smartphones move that is widely used, action cameras and Raspberry Pi’s. This type of card is compatible with SD via a simple adapter, which is often supplied as standard. For many other devices, there is little need to switch to micro-sd, because a product is not necessarily smaller. A smart phone may need to be as flat as possible, but for a camera, there is a lower limit in terms of size, because at a certain moment, it is not more pleasant to operate it and to hold it.

Sd memory has become very cheap. For about two bucks buy you a 64GB card with decent speed, but there are also cards with the same capacity five times the cost and in return can read and write faster. We were wondering how big the differences in practice or you really notice the speed difference and which card has the best price-performance ratio. Apart from the usual benchmarks, we have engaged a number of cameras in the test. In this case we see concrete or a camera really benefit from more expensive cards with higher speeds. Although there are two micro sd cards in the test are recorded, we focus cameras in mind in this article so especially on SD cards.
